Step-by-step explanation:
x² = 16
x = ±√16
x = ±4
x = -4 or 4
Answer:
13.6 gallons
Step-by-step explanation:
y = 2.72x
this means that 2.72 is multiplied by x
y = 2.72 * x
x = number of gallons
5 = number of gallons
5 = x
y = 2.72 * 5
y = 13.6 gallons
Answer:
![\frac{3x}{3 - 2x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%7D%7B3%20-%202x%7D%20)
Step-by-step explanation:
Here,
f(x) = y
![y = \frac{3x}{2x + 3}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B3x%7D%7B2x%20%2B%203%7D%20)
or , swapping x with y
![x = \frac{3y}{2y + 3}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B3y%7D%7B2y%20%2B%203%7D%20)
now to solve for y we get
![y = \frac{3x}{3 - 2x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B3x%7D%7B3%20-%202x%7D%20)
now we put f inverse x instead of y
![{f}^{ - 1} (x) = \frac{3x}{3 - 2x}](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7B3x%7D%7B3%20-%202x%7D%20)
I am done.
